What is an Exchange Rate?

An exchange rate is the price at which one currency can be exchanged for another. For example, if 1 USD = 0.92 EUR, then one US dollar buys 0.92 euros.

This page provides a manual calculator and a reference glossary for common exchange rate terms.

Frequently Asked Questions
Does this tool fetch live exchange rates?

No. You enter the rate manually. This tool focuses on the calculation and on explaining exchange rate concepts. For live rates, use your bank, Google Finance, or XE.com.

What is a bid/ask spread?

The bid price is what a buyer pays for currency; the ask price is what a seller charges. The spread (ask minus bid) is the broker's profit. A wider spread means higher transaction costs.

How do I find the exchange rate?

Search Google for the pair (e.g. "1 USD to EUR"), check your bank's rates, or use a service like XE.com or OANDA for live interbank rates.

What is a cross rate?

A cross rate is the exchange rate between two currencies that are both quoted against USD. For example, EUR/GBP can be derived from EUR/USD and GBP/USD.
